Here is the code for the countOccurrences method in the IntLinkedBag class:

public int count$0$ccurrences$($int target$)$

$\{$

int answer;

IntNode cursor;

answer $=0$;

cursor $=$ IntNode. listSearch$($head$,$ target$)$;

while $($cursor $!=$ null$)$

$\{//$ Each time that cursor is not null, we have another occurrence of

$//$ target, so we add one to answer and then move cursor to the next

$//$ occurrence of the target.

answer$++$;

cursor $=$ cursor $*getLink(,)$;

cursor $=$ IntNode. listSearch$($cursor$,$ target$)$;

$\}$

return answer;

$\}$

When this method is called and the target is not in the bag, how many times will the while loop be executed?
